Since the end of the 19th century, P-Traps have been used successfully for this purpose, for each incident enough water flows through the trap to move the waste from the source to the sewer while leaving water within the trap as a seal against air flow. With the trap set level and filled with water a test was run to see at what pressure the trap would cease to seal against air flow.
